I have been common law married to an abusive man man for 15 yrs can he just throw me out with nothing like he and his family are trying to do?

Texas is one of the few states that acknowledges common law marriage. You are actually entitled to a divorce and a division of any assets you two may have purchased together during the marriage (house, cars, retirement benefits, etc.) It is my hope that you have separated and that you are somewhere safe and away from him if he is abusive. Also, you did not mention if you have any children, but if you do, you would be entitled to certain rights and benefits as it pertains to them. You two may not have been formally married, but that doesn't stop you from pursuing a divorce and the rights associated with any community property you two may have.
